Y, A-further object of thev inventionfis to provide a new and efficient`process of constructing pilings Vwherebyrthel said pilings 'may be set'in place and constructed with a minimum offexpense.`

" VIn theI drawings which form a partlof application, Fig. 1 is atransverse'sectionaly View showing the piling'socket after having Y beendrilled with the drill pipe'and 'baglining inserted within the same; and

- The process of-constructinga piling to be embedded in land notcoveredwith water" will bel vfirstV described] The drill pipe 1 havingVthe usual form of cutter will be used to bore the piling socket 2 tothe desired vdepth, and thebase of the said socket may Vbe enlarged asat 3 to provide for aV suitable footing for the piling when in position.

It is customary when-theV holes for the pilings. are drilled gto placeacasinlgabout the interior thereof to `prevent the .walls of the holes'from caving Qin. .One of `the, main features of'my inventionis todispense with 'the use of these casings and `in lieuv thereof to fillthev socketV or hole 2 with soft mud for Y clay as the hole is beingdrilled.v The opening orl socket beingentirely filled'with the soft, mudor clay lpositively prevents any caving in of the walls.

When the desired depth for the opening is reached,'the drill pipe V1 iswithdrawn therefrom and a closely wovencanvas bagv or lining 4 is drawnover the said drill pipe as illustrated in Fig. 1 of the drawings. A

` plug 5 is secured to the lower endof the canvasbag or lining 4 in anysuitable man# ner;lthen it is inserted within the openV end canvaslining are forced down through the .Geenen AlinnssngkonivnwoRLnANs,cnonistarmi.`fk 'p mud or lclayffin: the; .2

From the foregoing description it will be apparentthat my process offorming pilings vWill enti-rely do 'away with the necessity of insertingthe. usual bracing casing in the holes to prevent caving 1n` of the same'as they are drilled', whicht feature alone makes a. greatsavingineXpense in thev construction of" the pilings.
